educational network to connect to linuxcnc

hi, i am new here.in fact i have successfully installed emc2 with a CD burnt. but i wonder how to install emc2 with **.sh.

i have uninstalled emc2, and follow the instruction about the installation.->to run **.sh in the terminal, then the terminal is trying to connect to hkt.edu and fetch a key~~then i wait ....the terminal shows that it cannot connect to linuxcnc. so i think it fail to fetch the key, then so does the emc2 fail to install~~? maybe that failure is due to the update sources?? i have configured my sources.list. in China we have many sources in camp for educational network~~but, when i update apt-get, whatever sources i use,it failed to connect to linuxcnc~~~OMG~

can anyone show me how ~??

at least show me how to install emc2 with this **.sh~! thx!

You will need a public key on your machine. That is why you are getting that message.

If you already havenn't looked at the Wiki, start here wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2

Also, log onto the IRC channel. if you go to the website, there is a link to a java client you can use or directions there to use your favorite IRC client.
